I think that this type of thing was the real issue that Pope Francis was trying to address in his exhortation Amoris Laetitiae. Is your spouse in agreement with the children being raised in the Catholic Church? Here are a few things to think about from the Code of Canon Law;
A few things to consider from the Code of Canon Law;
Can. 867 §1. Parents are obliged to take care that infants are baptized in the first few weeks; as soon as possible after the birth or even before it, they are to go to the pastor to request the sacrament for their child and to be prepared properly for it.
An important part of being properly prepared for your child's baptism is that you should be a member of the parish. You should at least regurly attend mass. If you cannot do this in good conscience then your child should not be baptized. Canon Law also says;
Can. 868 §1. For an infant to be baptized licitly:
1/ the parents or at least one of them or the person who legitimately takes their place must consent;
2/ there must be a founded hope that the infant will be brought up in the Catholic religion; if such hope is altogether lacking, the baptism is to be delayed according to the prescripts of particular law after the parents have been advised about the reason.http://www.vatican.va/archive/ENG1104/__P2X.HTM
How does your spouse feel about the two of you getting your marriage recognized by the Catholic Church?
